Close-up image of the "Berry Bowl" on Mars, a rock formation rich in small, hematite-rich spherules nicknamed "blueberries" by scientists.  These 4mm diameter orbs are embedded in and around the rocks, suggesting deposition from water. The image shows a circular patch of different composition in the underlying rock, providing clues to their origin.  Captured by the Opportunity rover on its 48th Sol.
